Statement Of Problem: Although intraoral scanners have been increasingly utilized as alternatives to conventional impression techniques, their precision in capturing the complex anatomy of prepared widened root canals, essential for post placement after endodontic treatment, remains underexplored.
Purpose: The purpose of this in vitro study was to assess the efficacy of different intraoral scanners in scanning widened root canals. The study analyzed the depth (mm) and surface area scanned (mm) and compared 2 scanning techniques.

Objectives: Describe the use and findings of cardiopulmonary imaging-chest X-ray (cX-ray), echocardiography (cEcho), chest CT (cCT), lung ultrasound (LUS), and/or cardiac magnetic resonance imaging (cMRI)-in COVID-19 hospitalizations in Latin America (LATAM).
Background: There is a lack of information on the images used and their findings during the SARS-CoV-2 pandemic in LATAM.
Methods: Multicenter, prospective, observational study of COVID-19 inpatients, conducted from March to December 2020, from 12 high-complexity centers, in nine LATAM countries.
Nitrate (NO3-) fertilisers are commonly used to improve the yield and quality of most non-legume crops such as potato (Solanum tuberosum L.). Root cells absorb nitrate from the soil using plasma membrane-bound transporters.

Although some countries have reduced asbestos consumption and instituted bans, other countries continue to produce and consume asbestos even as asbestos-related deaths mount and the associated societal costs are high. Asbestos production and consumption has declined globally; the number of bans has increased; and the speed at which countries have tapered off consumption has increased. Using country-level data, we study the economic impact of historical changes in the production and use of asbestos.

This report presents the results of a consensus process coordinated by the Pan American Health Organization/World Health Organization (PAHO/WHO), the United States Centers for Disease Control and Prevention (CDC), and the Latin American Society of Nephrology and Hypertension (SLANH). This consensus seeks to increase the probability of detecting and recording deaths from these causes.
